SPECIFICATION forming part of Letters Patent No. 731,627, dated June23,1903.

` Application filed December l, 1902. Serial No. 133,421. (No model.)

To @ZZ whom. t may concern: j

Be it known that I, JUSTIN SIGRIsT, a citizen of the United States,residing at the city of Battlecreek, in the county of Calhoun and. Stateof Michigan, have invented certain new and useful Improvements in Endsfor Vehicle-Shafts, of which the following is a speci- Iication.

This invention relates to improvements in required strength is securedwithout injury In the construction of shafts it is customary to finishleather.

It is the object of this invention to provide an improved end forvehicle-shafts, whereby a broken shaft may be repaired and theappearance of the ordinary shaft retained or the end of a new shaftfinished. A further object is to provide an improved end for shaftswhich is strong and durable and economical to construct and use.

Further objects will definitely appear in the detailed description tofollow.

I accomplish the objects of my invention following specification.

The inventionis clearly defined and pointed A structure embodying thefeatures of my invention is fully illustrated in the accompanyingdrawings, forming a part of this speci- Figure l is a side elevationview of a shaft end embodying the features of my invention.

of Fig. l, showing details of construction. Fig. 3` is a detaillongitudinal sectional view In the drawings the sectional views aretaken looking in the direction of the little arrows at the ends of thesection-lines, and similar letters of reference refer to similar partsthroughout the several views.

Referring to the letteredparts of the drawings, A is a tube suitablytapered formed of cured together by a double seam C. This tube isreinforced'by an inner tube B, formed of a strip of sheet metal, oneedge of which is clamped into the seam C, by whichthe edges of the metalforming the sheet A are united. i The other edge of the strip of sheetmetal forming the inner tube B is left free and terminates, preferably,at the edge of the seam C. The seam is prevented from 6o opening, andthe tubes are retained in proper relation to each other by anindentation C in the metal at the edge of the seam, so that it isimpossible to disengage't-he meeting edges of the metal forming theouter tube A, and the edge of the reinforcing-tube is prevented fromwithdrawing.

The inner tube B is slightly shorter than the outer tube A, andthe :endof thelouter tube is folded inwardly and clamped upon 7o the same at D,which securely clamps the inner tube in position and gives the structurea finished appearance, effectively removing any rough edges.

The inner tube preferably extends the entire length of the outer tube,though very satisfactory results are procured if it is extended only aportion of the way. The outer Iend ofvthe tube is provided with a plugof wood adapted to lit the same snugly, and its 8o inner end is adaptedto `fit over the end of the shaft and be secured thereto by rivets orthelike,suitable perforations, as a, being provided to receive the same.The usual shaft, tip A is provided for the outer end. By this 85arrangement of the parts they are securely and firmly united, and it ispractically impossible to open the seam by crushing or the like intransportation or handling. The liability of injuring thestructure inits application to the shaft is also reduced toa minimum, the partsbeing so firmlysecured; together. The structure is very strongand hasaneat and finished appearance. While itisdesigned particularly for repairpurposes, it is econom- 95 ical for use in new structures, as, owing tothe superior finish possible by this construction, it very closelyimitates the desirable leather finish.

I have illustrated and described my i-mroo proved end for shafts in theform preferred by me on account of its strength and economy inmanufacture.y I am aware-that it is capable of considerable structuralvariation without departing from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a. shaft end for vehicles, the combination of an outer tube Aconsisting of a strip of sheet metal with its edges secured together bya double seam C; an inner tube B fitting snugly within the outer tube,the said inner tube consisting of a strip of sheet metal, one edge ofwhich is clamped by said seam C, the inner end of said outer tube beingfolded inwardly and clamped upon the said inner tube; an indentation Cin said tubes through the inturned part and at the side of said seam,whereby said parts are retained in position; and a suitable filling-plugin the out-er end of said tubes, substantially as described.

2. In a shaft end for vehicles, the combination of an outer tube Aconsisting of a strip of sheet metal with its edges secured together bya double seam C; an inner tube B fitting snugly within the outer` tube,the said inner tube consisting of a strip of sheet metal, one

edge of which is clamped by said seam C; an-

indentation C in said tubes at the side of said seam, whereby said partsare retained in position and a suitable filling-plug in the outer end ofsaid'tubes, substantially as described.

3. In a shaft end for vehicles, the combination of an outer tube Aconsisting of a strip i of sheet metal with its edges secured togetherby a double seam C; an inner tube B fitting snugly within the outertube, the said inner tube consisting of a strip of sheet metal; an

` indentation C in said tubes at the side of said seam, whereby saidparts are retained in position; and a suitable filling-plug in the outerend of said tubes, substantially as described.

4. In a shaft end for vehicles, the combination of an outer tube Aconsisting of a strip of sheet metal with its edges secured together bya double seam C; an inner tube B fitting snugly within the outer tube,the said inner tube consisting of a strip ot' sheet metal, one edge ofwhich is clamped by said seam C, the inner end of said outer tube beingfolded inwardly and clamped upon said inner tube whereby said parts areretained in position; and a suitable filling-plug in the outer end ofsaid tubes, substantially as described.

5.- In a shaft end for vehicles, thecombina# tion of an outer tube Aconsisting of a strip of sheet metal with its edges secured together bya double seam C; an inner tube B fitting snugly Within the outer tube,the said inner tube consisting of a strip of sheet metal, the inner endof said outer tube being folded inwardly and clamped upon said innertube, whereby said parts are retained in position; and a suitablefilling-plug in the outer end of said tubes, substantially as described.

In Witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
